Total mass and luminosity of star forming regions in the LMC: Predicted infrared fluxesWe have investigated 4 Shapley constellations (1996, A&A , 308 , 40) to define the associated stellar complexes and their properties. From observed star counts and recent spectral classification we derive an ...

In agreement with the one previous study of the luminosity-metallicity (LZ) relation in paired galaxies, we find an offset to lower metallicities (by ~ 0.1 dex) for a given luminosity for galaxies in pairs compared to the control sample. We also present the first mass-metallicity (MZ) ...
Interestingly, the star has a supergiant appearance (luminosity class I) even at the ZAMS. We find the following evolutionary sequence of spectral types: O3 I (at the ZAMS), O4 I (middle of the H-core burning phase), B supergiant (BSG), B hypergiant (BHG), hot luminous blue variable ...
When we are classifying stars into different categories, we do this via two different methods. The first method is the Harvard method; this is done by using the stars surface temperature. The second method is known as the MK method, which we classify stars based on their luminosity. It can...
Star - Fusion, Mass, Energy: To interpret a stellar spectrum quantitatively, knowledge of the variation in temperature and density with depth in the star’s atmosphere is needed. Some general theoretical principles are outlined here. The gradient of tem
